Brief Answer:
pills or may not be the cause...

Detailed Answer:
Hi,

Nausea is one of the common symptoms reported before onset of periods. And morning after pill is known to transiently upset the rhythm of menstrual cycle. You've may have had an early or delayed period the last time. The cycle will remain disturbed this time too. In my opinion the nausea could be related to the premenstrual symptom and not pregnancy.

Rest be assure if you've had a regular period, it invariably rules out pregnancy. Moreover you have also had 3 pregnancy test which were all negative. So based on all these facts I have considerably ruled out all possibilities of pregnancy.

Further, I will expect you to be back to your normal self during the next menstrual cycle.

Hope this helps. Let me know if you need more clarifications.

Regards
